[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1-9 As shown, an embodiment of the present invention provides a circuit board anti-slip pressing carrier, comprising: refer to Figure 2 The chassis 1 provides a placement position for the circuit board; the lower surface of the chassis 1 is provided with an embedding groove 101. The embedded slot 101 is elongated and does not affect the placement of the circuit board on the chassis 1.

[0020] Through hole 2, the base 1 is located at the edge of the base 1 to provide an installation position; refer to Figure 3 , Figure 7 Anti-slip component 5 is mounted on chassis 1 to prevent the circuit board from sliding. Anti-slip component 5 includes anti-slip base block 501. Two rotating seats 502 are fixedly connected to the outer side of anti-slip base block 501. Anti-slip rotating arm 504 is rotatably connected to rotating seat 502. Locking claw 505 is provided at the upper end of anti-slip rotating arm 504. Locking groove 503 is provided at the end face of anti-slip base block 501. Locking claw 505 can engage with locking groove 503. When providing anti-slip operation for the circuit board, the anti-slip rotating arm 504 has three states. In the first state, both anti-slip rotating arms 504 are open, the locking claw 505 is not engaged with the locking groove 503, and the two anti-slip rotating arms 504 are in a "V" shape, both of which can provide a restraining effect to prevent the circuit board from sliding when placed on the chassis 1. At this time, the distance between the restraining contact points between the two anti-slip rotating arms 504 and the circuit board material is relatively large when the circuit board material is just released. The friction force between the circuit board material and the anti-slip rotating arm 504 is more dispersed, and the circuit board material falls more smoothly. This avoids the circuit board material being damaged due to excessive concentration of frictional resistance, which would exceed the toughness of the circuit board material. This design can improve the integrity of the circuit board material after release and ensure the good quality of the circuit board product. As the circuit board material falls, its position becomes more accurate than when it was first placed due to the restriction of the anti-slip rotating arm 504. Therefore, the limiting pressure and friction between the circuit board material and the anti-slip rotating arm 504 decrease. As it approaches the chassis 1, even if the limiting contact points between the anti-slip rotating arm 504 and the circuit board material get close to each other, the relatively small friction will not damage the circuit board material. The circuit board material can land smoothly and accurately on the chassis 1, which is beneficial for the release of the ultra-thin circuit board material and ensures the good quality of the circuit board product. The second state is that one anti-slip rotating arm 504 is open and the other anti-slip rotating arm 504 is closed. Specifically, the locking claw 505 of one anti-slip rotating arm 504 is engaged with the locking groove 503, while the locking claw 505 of the other anti-slip rotating arm 504 is not engaged with the locking groove 503. At this time, the open anti-slip rotating arm 504 will be in a state with a larger opening angle under the action of the elastic component 7. The angle between the open anti-slip rotating arm 504 and the anti-slip base block 501 is larger. At this time, it can provide anti-slip function for thicker multilayer circuit boards. The third state is that both anti-slip rotating arms 504 are closed, both locking claws 505 are engaged with locking grooves 503, and the locking claws 505 are in a horizontal state, which can provide anti-slip function for circuit boards with smaller thicknesses; the three states are suitable for the pressing operation of circuit boards of three thicknesses, avoiding slippage of the circuit board and improving the pressing accuracy.

[0021] refer to Figure 3 , Figure 4The fixing component 3 is located at the through hole 2 and is used to fix the anti-slip component 5. The fixing component 3 includes an upper fixing seat 301 and a lower fixing seat 305. The upper fixing seat 301 is provided with a fixing hole 302. A side plate 303 is fixedly connected to the edge of the upper fixing seat 301. The fixing hole 302 is threadedly connected to the lower fixing seat 305 through the through hole 2 by a fixing screw 304. The lower fixing seat 305 is adapted to the embedded groove 101. During the fixing operation, multiple fixing screws 304 are passed through the through hole 2 and tightened to be threadedly fixed to the lower fixing seat 305, so as to realize the function of installation on the chassis 1.

[0022] refer to Figure 3 , Figure 6 Adjustment component 4 is mounted on fixed component 3 and is used to adjust the position of anti-slip component 5. Adjustment component 4 includes a bidirectional lead screw 401 rotatably mounted between two side plates 303, an adjustment slide rod 404 fixedly connected between the two side plates 303, an operating handle 402 fixedly connected to the end of the bidirectional lead screw 401, two adjustment seats 403 slidably connected to the adjustment slide rod 404, both adjustment seats 403 being threadedly engaged with the bidirectional lead screw 401, and adjustment arms 405 rotatably connected to the lower part of each of the two adjustment seats 403. A center seat 406 is provided between the two adjustment arms 405, and the center seat 406 is rotatably engaged with the adjustment seats 403. The center seat 406 is fixedly connected to the anti-slip base block 501. During adjustment, the double-acting lead screw 401 is rotated by operating handle 402, which causes the two adjustment seats 403 to slide closer to each other on the adjustment slide bar 404. The two adjustment seats 403 drive the adjustment arm 405 to move, which in turn drives the center seat 406 to move, which in turn drives the anti-slip base block 501 to move, thus adapting to circuit boards of different sizes and making it applicable to a wider range of applications. Adjustment component 4 provides the function of adjusting the position of anti-slip component 5. The distance can be various, such as 1 cm, 2 cm, or 3 cm between anti-slip component 5 and fixed component 3. As long as it is within the adjustment range of adjustment component 4, it can be achieved. It does not provide a single fixed distance position. Therefore, it is more flexible and convenient to use, and has a wide range of applications.

[0023] refer to Figure 3 , Figure 7 , Figure 8An extension component 6 is provided on the anti-slip component 5 to provide an extension function. The extension component 6 includes an extension groove 601 on the side of the anti-slip rotating arm 504. An extension block 602 is slidably connected in the extension groove 601. An extension claw 603 is fixedly connected to the extension block 602. A control part 604 is provided at the top of the extension claw 603. The control part 604 can be retracted into the anti-slip rotating arm 504. A permanent magnet 605 is fixedly connected to the bottom of the extension block 602. The permanent magnet 605 can be attracted to the inner wall of the extension groove 601. A locking screw 606 is provided at the top of the anti-slip rotating arm 504. The locking screw 606 can lock the extension claw 603. To increase the limiting range of the anti-slip function, an extension operation can be performed. Specifically, first, loosen the locking screw 606, and use external force to drive the extension claw 603 through the control unit 604. The extension claw 603 drives the extension block 602 to move along the extension groove 601, so that the extension claw 603 can extend outward. Then, the permanent magnet 605 attracts the extension groove 601, and then the locking screw 606 is tightened to fix the extension claw 603. The extension claw 603 provides a higher limiting surface, which is suitable for circuit boards with greater thickness. During the production process, circuit board materials are typically placed automatically on the chassis 1 by a robotic arm using suction cups. Since circuit board products have multiple layers, and the more layers there are, the thicker they become, the design of the extension claw 603 is essential to accommodate the thickness of the circuit board and the height requirements for the robotic arm to release the material. This extension claw provides excellent guidance for the release of the circuit board material and can accommodate thicker circuit boards, preventing the robotic arm from failing to provide adequate guidance when releasing the material due to insufficient guidance height. This ensures accurate placement of the circuit board material and improves the quality of the circuit board product. The extension component 6 works in conjunction with the anti-slip component 5, further dispersing the frictional force between the anti-slip rotating arm 504 and the circuit board material in the first state of the anti-slip component 5, thus improving the function of preventing deformation damage to the circuit board material.

[0024] refer to Figure 7 , Figure 8 Elastic component 7 is disposed on anti-slip component 5 and is used to provide elastic connection function; elastic component 7 includes elastic groove 701 disposed on anti-slip rotating arm 504, elastic slider 702 is slidably connected in elastic groove 701, and a horizontal spring 703 is rotatably connected between the two elastic sliders 702. When no external force is applied to the two anti-slip rotating arms 504, the elastic force provided by the horizontal spring 703 balances the weight of the anti-slip rotating arms 504, controlling both anti-slip rotating arms 504 to be in the open state and to maintain a stable state. When one of the anti-slip rotating arms 504 is closed, the horizontal spring 703 is stretched. The elastic slider 702 on the closed anti-slip rotating arm 504 slides down along the elastic groove 701, and the elastic slider 702 on the open anti-slip rotating arm 504 slides up along the elastic groove 701. This allows the other open anti-slip rotating arm 504 to open to a larger angle and remain stable under the support of the horizontal spring 703, thus achieving flexible switching between the three states.

[0025] refer to Figure 5 , Figure 6 Locking component 8 is disposed on fixing component 3 and is used to provide locking function; locking component 8 includes end plate 801, locking rod 802 is fixedly connected to end plate 801, locking spring 803 is sleeved on locking rod 802, locking rod 802 is slidably engaged with side plate 303, locking plate 804 is fixedly connected to the outer end of locking rod 802, locking cavity 805 is provided on locking plate 804, and locking spring 803 is located between locking plate 804 and side plate 303; To prevent the bidirectional lead screw 401 from rotating and to ensure the stability of the anti-slip position, a locking operation can be performed. Specifically, under the elastic force of the locking spring 803, the locking plate 804 can be supported, causing the operating handle 402 to be engaged in the locking cavity 805. The locking cavity 805 is used to lock the operating handle 402, thereby preventing the bidirectional lead screw 401 from rotating. If it is necessary to rotate the operating handle 402, external force presses the locking plate 804, compresses the locking spring 803, and the operating handle 402 moves out of the locking cavity 805. Therefore, the operating handle 402 can rotate normally.

[0026] Working principle: When providing anti-slip operation for the circuit board, the anti-slip rotating arm 504 has three states. In one state, both anti-slip rotating arms 504 are open, the locking claw 505 is not engaged with the locking groove 503, and the two anti-slip rotating arms 504 are in a "V" shape, which can provide a limiting effect and prevent the circuit board from sliding when placed on the chassis 1. The second state is that one anti-slip rotating arm 504 is open and the other anti-slip rotating arm 504 is closed. Specifically, the locking claw 505 of one anti-slip rotating arm 504 is engaged with the locking groove 503, while the locking claw 505 of the other anti-slip rotating arm 504 is not engaged with the locking groove 503. At this time, the open anti-slip rotating arm 504 will be in a state with a larger opening angle under the action of the elastic component 7. The angle between the open anti-slip rotating arm 504 and the anti-slip base block 501 is larger. At this time, it can provide anti-slip function for thicker multilayer circuit boards. The third state is that both anti-slip rotating arms 504 are closed, both locking claws 505 are engaged with locking grooves 503, and the locking claws 505 are in a horizontal state, which can provide anti-slip function for circuit boards with smaller thickness; the three states are suitable for the pressing operation of circuit boards of three thicknesses, avoiding slippage of the circuit board and improving the pressing accuracy. When external force presses on the locking plate 804, it compresses the locking spring 803, and the operating handle 402 moves out of the locking cavity 805. Therefore, the operating handle 402 can rotate normally. The operating handle 402 drives the bidirectional lead screw 401 to rotate, causing the two adjusting seats 403 to slide closer to each other on the adjusting slide bar 404. The two adjusting seats 403 drive the adjusting arm 405 to move, which in turn drives the center seat 406 to move, which in turn drives the anti-slip base block 501 to move. The anti-slip base block 501 is in close contact with the side of the circuit board, which can adapt to circuit boards of different sizes and has a wider range of applications. Under the elastic force of the locking spring 803, it can provide support for the locking plate 804, so that the operating handle 402 is inserted into the locking cavity 805. The locking cavity 805 locks the operating handle 402, thereby preventing the bidirectional lead screw 401 from rotating. To increase the limiting range of the anti-slip function, an extension operation can be performed. First, loosen the locking screw 606, and use external force to drive the extension claw 603 through the control unit 604. The extension claw 603 drives the extension block 602 to move along the extension groove 601, so that the extension claw 603 can extend outward. Then, the permanent magnet 605 attracts the extension groove 601, and then the locking screw 606 is tightened to fix the extension claw 603. The extension claw 603 provides a higher limiting surface, which is suitable for thicker circuit boards.
